Responses of Collembola and Protura to tree girdling – some support for ectomycorrhizal feeding
Ectomycorrhizal (EM) fungi are very common in forest soils, but their role as a food resource for fungivorous soil animals is poorly known. We used two tree-girdling experiments in Picea abies forests and one experiment in a Pinus sylvestris forest, all in northern Sweden, to indirectly test if Coll...

Ectomycorrhizal (EM) fungi are very common in forest soils, but their role as a food resource for fungivorous soil animals is poorly known.

We assumed that tree girdling will stop the flux of carbohydrates to roots and associated fungi, and thereby inhibit growth and long-term survival of EM fungi.
